Product details
Overview
IRG4PSH71U from Infineon Technologies (formerly International Rectifier) is a 1200V, 99A n-channel UltraFast IGBT in Super-247 (TO-274AA) package, optimized for hard-switching up to 40kHz and resonant soft-switching up to 200kHz. It delivers VCE(on) = 2.50V @ 15V gate drive and 50A, RθJC = 0.36°C/W, and 150mJ reverse avalanche energy - enabling high-efficiency motor drives and industrial UPS inverters.
For engineers reviewing the IRG4PSH71U datasheet, IRG4PSH71U pinout, IRG4PSH71U application, or IRG4PSH71U equivalent, key selection criteria include its 1200V blocking rating, ultra-low switching losses (Eon = 4.77mJ, Eoff = 9.54mJ @ 70A/960V), tight parameter distribution from Gen4 IGBT design, and creepage distance of 5.35mm for reinforced isolation in high-voltage systems.
Technical Context
This Generation 4 IGBT employs field-stop trench-gate structure to minimize conduction and switching losses simultaneously. Its 7280pF input capacitance (Cies) and low 50pF reverse transfer capacitance (Cres) support fast, controllable turn-on/turn-off with minimal Miller effect - critical for ZVS/ZCS topologies in high-frequency SMPS and induction heating.
The device integrates internal emitter inductance of 13nH and supports clamped inductive load testing at 200A with 150mJ avalanche energy rating. Thermal design is enabled by validated junction-to-case resistance of 0.36°C/W and recommended clip force of 20N for reliable heat transfer in high-power modules and stacked heatsink assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200V - Enables direct use in 690V AC three-phase rectified bus (≈975V DC) with 22% margin for transients. |
| IC @ TC = 25°C | 99A - Supports continuous 50–70kW inverter output with forced-air cooling and 20N mounting pressure. |
| VCE(on) | 2.50V @ 15V/50A - Delivers <125W conduction loss at rated current, reducing heatsink size vs. prior-gen IGBTs. |
| Etot | 14.3–15.8mJ @ 70A/960V - Enables >97% efficiency in 20kHz hard-switched PFC stages with 5Ω gate resistor. |
| RθJC | 0.36°C/W - Allows 100W dissipation with ≤36°C case-to-junction rise, compatible with standard copper-base heatsinks. |
| Cres | 50pF - Minimizes voltage-dependent gate charge feedthrough, improving noise immunity in high-dV/dt environments. |
| Creepage | 5.35mm - Meets IEC 61800-5-1 reinforced insulation requirements for 1000V DC systems. |
Pinout & Package
IRG4PSH71U uses the Super-247 (TO-274AA) package: insulated metal baseplate, 20.8mm × 14.8mm footprint, 4.25mm height, 6g weight, and JEDEC-compliant outline with creepage-enhanced molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – Gate | Control terminal | Low-impedance MOS gate requiring 370–560nC total charge; sensitive to ESD; must be driven with ≤5Ω series resistance for controlled dV/dt. |
| 2 – Collector | High-side power output | Connected to DC bus positive; carries full load current and fault currents up to 200A pulse; electrically isolated from case. |
| 3 – Emitter | Power return / reference node | Serves as common source for gate drive return and current sensing; low-inductance path critical for stable switching waveforms. |
| 4 – Collector (tab) | Main power output terminal | Exposed metal tab is collector-connected; provides primary thermal path to heatsink; requires insulating pad or ceramic washer when mounted to grounded chassis. |
Key Features
| Feature | Design Value |
|---|---|
| UltraFast switching | Turn-off delay td(off) = 280–390ns and fall time tf = 170–360ns enable clean 40kHz hard switching without snubbers. |
| Gen4 parameter uniformity | Tight VGE(th) (3.0–6.0V) and ∆VGE(th)/∆TJ (−9.2mV/°C) allow parallel operation without current imbalance above 125°C. |
| Super-247 power density | Twice TO-247 power handling in same footprint - enables compact 3-phase inverter designs with reduced PCB area and interconnect inductance. |
| Clamped inductive ruggedness | Rated for 200A ILM and 150mJ EARV - withstands unclamped inductive turn-off events in motor drive short-circuit conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN75N120B3 | 1200V/75A, TO-247 package, higher VCE(on) = 2.8V, RθJC = 0.45°C/W | Limited to ≤30kW due to lower current rating and thermal resistance | Select when cost sensitivity outweighs power density; requires larger heatsink and derating above 85°C case temp. |
| STMicroelectronics STGW100H12DL | 1200V/100A, HiPak package, integrated NTC, VCE(on) = 2.45V, but Cres = 72pF | Better conduction loss but higher Miller capacitance increases gate drive complexity | Prefer for space-constrained designs needing temperature monitoring; avoid in high-dV/dt noise environments without extra gate filtering. |
Compared with IXGN75N120B3 and STGW100H12DL, IRG4PSH71U offers superior power density (twice TO-247 current in same footprint), lowest Cres, and highest creepage - making it optimal for compact, high-reliability industrial inverters where thermal management and EMI robustness are critical.

FAQ
What gate drive voltage and resistance are recommended for IRG4PSH71U?
IRG4PSH71U requires ±20V absolute maximum gate voltage, with typical turn-on at 15V and turn-off at −5V to −8V. A 5Ω series gate resistor is validated for 70A/960V switching with td(off) = 280ns and Eoff = 9.54mJ; lower resistance (<3Ω) increases dI/dt but risks oscillation without proper layout.
Can IRG4PSH71U replace older IRG4PHxxU series IGBTs in existing designs?
Yes - IRG4PSH71U is a direct drop-in replacement for IRG4PH71U with identical Super-247 pinout, improved VCE(on) (2.50V vs. 2.65V), tighter parameter spread, and enhanced avalanche ruggedness (150mJ vs. 120mJ). No layout or gate drive changes are required for upgrade.
What is the maximum allowable case temperature for continuous operation?
IRG4PSH71U supports continuous operation up to TC = 100°C, delivering 50A IC and 140W PD. At this temperature, VCE(on) rises to 2.68V (at 70A), and switching losses increase by ~40% versus 25°C - thermal design must ensure junction stays ≤150°C under worst-case ambient and load.
Does IRG4PSH71U include an anti-parallel diode?
No - IRG4PSH71U is a discrete IGBT only. It does not integrate a freewheeling diode. External ultrafast or SiC Schottky diodes (e.g., IDH08SG60C) must be used in antiparallel configuration for inductive load commutation and regeneration paths.
